Set the labelitem property of the layer to null.

Right, just incase this is useful for anyone - I have managed to do a
bit of a hacky solution to turning the labels off:
I set the 'labelrequires' option of the layers to evaluate true if I
wanted the label to be drawn and false if I didn't.
Thus:
$layerObj = $map->getLayerByName($name);
$layerObj->set("labelrequires", "1 == 1");
turns the label on for layer $name.
and....
$layerObj = $map->getLayerByName($name);
$layerObj->set("labelrequires", "1 == 2");
Turns it off.
It feels a bit of a hack, so if anyone has anything more elegant
I'd be
happy to hear it.

Thanks Norbert, thats certainly an option (which I hadn't thought
of!)
and I may do that - I was just hoping that I would be able to find a
way to do with Mapscript (so I don't have to have such a huge
mapfile!)

Hi,
I'm not sure if this is what you want but you can make a layer for
the data and a separate one for the labels then you can turn them on
or off.

Hi all,
I am trying to use Mapscript to turn off labels 'on-demand'. I have
my label information set up in my mapfile - but this means that they
are always drawn. I want to retain that information in the mapfile
(rather than recreating the whole thing with Mapscript), so was
wondering if there was a way to tell Mapserver if they should be
drawn or not (without turning the whole layer off!). I have tried
using a 'STATUS OFF' within the label tags, but that doesn't work
(of
course!).
Any ideas?
Stu
